Bok Choy

Also called Chinese cabbage

In a nutshell

Bok choy is a crunchy, mild green that shines when stir-fried.

Bok choy, also called pak choi, is a Chinese cabbage with thick, juicy white or pale green stems and dark, spoon-shaped leaves. It tastes fresh, mild and gently sweet, with a faint peppery, mustardy note from its brassica family and a lot of crunch in the stalks. Baby bok choy is smaller, more tender and even milder.

Cooks love it because it gives two textures in one vegetable: crisp, watery stems and soft, silky leaves. It takes only a couple of minutes in a hot wok with garlic and ginger, soaks up soy, oyster and sesame flavours, and slips easily into noodle soups, braises and steamed dishes.

Good to know

Origin: China

Forms: whole, baby bok choy, shredded

Season: Available year-round; bok choy is a cool-weather crop at its sweetest in autumn and spring.

Nutrition: A leafy green vegetable that adds vitamins, minerals and fibre to a meal with very few calories.

Storage: Store bok choy unwashed in a loosely closed plastic bag in the crisper drawer and use it within 4–6 days; the leaves wilt faster than the stems. Wash it only just before cooking, separating the stalks or soaking halved baby heads in cold water to float out grit trapped near the base. Yellowing leaves, limp stems or a sour smell mean it is past its best. It can be frozen after a 1-minute blanch for up to 6 months, but it will be soft, so use frozen bok choy in soups and braises.

How to use bok choy

Stir-Frying Bok Choy

Flash-cook on high; the sugars in the stalks caramelize, sweetening each bite while staying crisp.

Steaming Bok Choy

Steam briefly; it tightens the cell walls, so it keeps both its green color and crunch.

The science of bok choy

Like cabbage and mustard, bok choy contains glucosinolates. When the cells are damaged, the enzyme myrosinase converts them into mildly pungent isothiocyanates, which give raw bok choy its faint peppery edge. Brief cooking keeps this note gentle and fresh.
The stems are mostly water held in rigid cells. Fast, high-heat stir-frying heats the surface quickly so the stems stay crunchy, while long or crowded cooking lets them release water and stew into limp, soggy pieces.
Bok choy leaves are thin and full of chlorophyll. A minute or two of heat keeps them bright green, but long cooking or adding vinegar early converts the chlorophyll into dull olive pigments.
In a very hot wok, the cut faces of halved baby bok choy brown through the Maillard reaction, adding a nutty, toasty depth that balances the clean, sweet stems.

How to choose bok choy

Look for firm, crisp, unblemished white or pale green stems and fresh, dark green leaves with no yellowing, holes or slimy patches. The heads should feel heavy and tight. Baby bok choy is best for halving and cooking whole; larger heads are good for slicing into stir-fries and soups.
